The so-called “Pizza Boy Rapist” pleaded not guilty to rape and burglary yesterday as police released his creepy, barely literate, handwritten confession.

“Cesar got type of disea in away he never had felted before . . . So then him self starts to check for open apartment, ” Cesar Lucas, 16, of The Bronx, allegedly wrote, recalling entering a sleeping woman’s unlocked apartment on West 61st Street early on a September morning after delivering a pie to another floor.

“So then he just approach her with this type of feelings he had never felted before which led him to do things he would never think he would do in his life.”

“I unrap her from all the coushing she had on top of her . . . She also started to feel horny, you can say,” the confession reads.

“She was completely drunk,” it claims.

“I really was pretty scare because she was drunk and I kind ah took advantage of her.”

He kept his eyes cast down at the defense table but lifted his head briefly to speak the words “Not guilty” in a strong, defiant voice.

Lucas’ lawyer, Gary Villanueva, explained, “He’s just a kid saying not guilty in a way that was comfortable for him.”

The teen worked for his father’s pizzeria on the same street as the attack.

The woman was raped as her 7-year-old daughter slept next to her in the bed. Afterward the attacker stole $20 from the little girl’s purse, authorities said.

Lucas initially denied the rape — but not the break-in — when he was arrested shortly afterward, according to police statements released after yesterday’s not-guilty plea.

“What’s going on? Why are you arresting me? I’ve been arrested before for the same thing. I broke into an apartment. It’s still pending. I have to go to court,” he is quoted as saying.

It was apparently a reference to burglary charges from a month before, when he allegedly crept into a sleeping woman’s West 42nd Street apartment — again while delivering pizza — and swiped her wallet. He has pleaded not guilty to that burglary.

Lucas eventually told authorities he committed the rape but put all the blame on his otherwise undescribed “disea,” cops say.

“Cesar didn’t realized what kind of things he was about to do or make,” the confession reads.
